But the new revelation illustrates that the Russian propaganda campaign may have been even wider still.

According to The Washington Post, the Google adverts tried to “spread disinformation,” and were a multi-pronged approach. They appeared on Google Search, as well as Gmail, YouTube, and DoubleClick adverts.

The total advert spend by “Russian agents” identified was reportedly less than $100,000, and it’s not clear if some came from “legitimate Russian accounts.” It’s not clear how many adverts there were, or how many times they were clicked on.

And on Sunday, The Daily Beast reported that Russia recruited YouTubers to “bash” Hillary Clinton, highlighting a pro-Donald Trump YouTube channel that it alleges was backed by the Russian government and was previously banned from Facebook and YouTube.

Google did not immediately respond to Business Insider’s request for comment.

Facebook found roughly 3,000 adverts adverts linked to Russia – but it has refused to publicly release them despite calls from congressional investigators. This is because investigations including special prosecutor Robert Mueller’s investigation is hindering it from releasing the ads, Business Insider previously reported.

In a blog post in September, Facebook chief security officer said that the “ads and accounts appeared to focus on amplifying divisive social and political messages across the ideological spectrum.”
